Larry Dignan and George Ou compared security warnings and severity between Windows XP/Vista and OSX. For sake of fairness, warnings affecting multiple versions (XP and Vista, 10.4 and Leopard) are counted once. The loser? Apple.
[T]his shows that Apple had more than 5 times the number of flaws per month than Windows XP and Vista in 2007, and most of these flaws are serious. Clearly this goes against conventional wisdom because the numbers show just the opposite and it isn’t even close.
Also noteworthy is that while Windows Vista shows fewer flaws than Windows XP and has more mitigating factors against exploitation, the addition of Windows Defender and Sidebar added 4 highly critical flaws to Vista that weren’t present in Windows XP. Sidebar accounted for three of those additional vulnerabilities and it’s something I am glad I don’t use. The lone Defender critical vulnerability that was supposed to defend Windows Vista was ironically the first critical vulnerability for Windows Vista.
